The kitchen and appliances
For a real homebody, one of the many pleasures in a real home is a fully-equipped kitchen. Cooking away from home also takes on a special sense for some people. Providing a well-equipped kitchen for your guests certainly adds appreciation points for you.
Make sure the major appliances work. Knives need to be sharp. Pots and pans have to be ready for use. Those tools and cleaning supplies have to be in one easy-to-find place.
It is a good idea to stock up on oils, vinegar, flour, salt, sugar and other basic condiments for home cooking. Keep your cookbooks and favorite recipes within easy reach.
You may write notes to your guests on where to buy the freshest fish, the best butcher, where to find bargains, and where the best restaurants are.
A leaky faucet would really have to be repaired, as much as that busted bulb has to be replaced. The wooden shed with peeling paint at the back of the house need not be repainted. Some sprucing up, of course, goes a long way.
Do you need to re-grout the bathroom tiles?
Is the kitchen sink dripping?
Does that linen closet really need repainting?
Where did that toilet paper holder in the downstairs bathroom go?
Is it time to shampoo the carpets?
In the end, you will notice your home had taken on a new attractive livable look, beautiful as it may have been before the streamlining and the sprucing up.
Finally, you may notice that all the repairs and the sprucing up were really how to make your home work (and look) good for you, and not just for your home exchange guests. As you may have noticed, that is the best part.
